it appears in 2021.1 UnityEngine.Input class is missing ???

i am confuse

I make the project, and now this is gone, I use for debug, quickly, UnityEngine.Input.GetKeyDown, etc.

but I see this is gone for newer unity version

and in 2019.4 it remains fine.

how to quickly call keyboard commands for debug purpose in newer unity, i am maybe going mad I do not understand this is missing, also no legacy class anywhere

is this stripped now from UnityEngine API ver 2021.1 + ???

No. All Unity version contain the UnityEngine.Input class including 2021.x and 2022.1.

Could it be disabled input module in package manager?
